''Invalid FTP buffer'' error when trying to connect to ftp server

[Louca]

Hey guys!

Been out of the run for Chevereto for about 10 months now but i'm back!
Anyway, I've been having this issue when trying to connect to a ftp server, whenever I try to save the ftp server settings I get a ''Invalid FTP buffer'' error.
I have Googled around a bit but that just lead to nothing unfortunatly, sooo, does anyone here have any idea how to fix it?
Below are my ftp settings with the obvious things being blurred out:


I have opened the ports, checked the ftp server via Filezilla (working correctly) and allowed the ftp client trough firewall.


Many thanks!

Edit: All credentials are correct by the way.

Does it happens with all FTP servers or just a few?

This is the only FTP server so I don't know, I have tried finding other FTP servers online but could not find any (like, at all).

The server should be ftp:// not http://
I use SFTP and I just put the ip address and nothing else in that field.

I have tried both http, ftp, and only the ip. I can see that the external server is connection to the ftp server, so the connection is working. Can you maybe explain me what invalid ftp buffer means so I know where to look 🙂, thanks!
